Analysis of the accuracy of GPS Trimble Juno ST measurement in the conditions of forest canopy
Original language description
GPS Trimble Juno ST was tested on 16 points under the forest growth canopy. The measurements were made in three different seasons of growth in 2007 and 2008. In each season, 4 recordings were measured in the length of 1, 2, 5 and 10 minutes with the recording frequency of 5 seconds. The resultant data were statistically evaluated by analysis of variance (ANOVA) both for data before corrections and for data after post-process corrections from the reference station. The tested GPS receiver reaches the average mean square error of the measurement of XY coordinates in the interval of 2.7 up to 5.1 m (without corrections and depending on the time of observation). Error of the altitudinal (Z) coordinate measurement is three times the average MSE XY. The useof corrections from reference stations turns out to be non-effective. No statistically significant relationship was proved between the PDOP value and the error of measurement of the position or height, as well as no significant relationsh
